ttc after miscarriage

Our miscarriage was a week ago. We are ready to start trying again, we use preseed and I'm taking prenatal vitamins. I have EXTREMELY irregular periods. I read somewhere to take baby aspirin also? I'm going to start both prenatal and baby aspirin today. We use preseed as well, is there Anything that could help us conceive faster? Maybe something over the counter? (I'm taking baby aspirin because I was told by a family member that because my periods are so irregular I'm not shedding my lining when I don't have a period so it's harder for the baby to stick) ANY HELP would be appreciated. We really want a baby 😞
